Beschreibung
Zusammenfassung:	The utility model relates to an anti-explosion overflow valve which comprises a valve body, a valve body hole axially formed in the valve body, a valve sleeve arranged in the valve body hole and a conical valve element. The conical valve element and the valve sleeve are in conical face sealing. A valve sleeve hole is axially formed in the valve sleeve, a sliding rod is arranged in the valve sleeve hole in a sliding mode, the sliding rod is formed by two portions, the upper portion of the sliding rod is connected with the lower end of the conical valve element, the lower portion of the sliding rod is matched with the wall face of the valve sleeve hole, the upper end of the conical valve element is connected with a valve element rod, and the valve element rod is sleeved with a pressure regulation spring. Under the condition that structure and use conditions are allowable, the pressure regulation spring with large rigidity is selected, vibration frequency and vibration amplitude are reduced, and noise is lowered
